Description

Technical Field

[0001] The utility model relates to the technical field of planetary gears, in particular to a planetary gear bracket. Background Art

[0002] Planetary gears are gear systems that can rotate around their own axes like fixed-axis gears, but their axes can also rotate around the axes of other gears along with the planet carrier. Rotation around their own axes is called "rotation", and rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name.

[0003] The planetary gear bracket is suitable for mounting planetary gears, also known as a planetary carrier. The existing planetary gear bracket has some shortcomings during use, such as the installation position of the planetary gears is fixed, which is not easy to adjust and has poor flexibility. For this reason, we propose a new type of planetary gear bracket. Utility Model Content
